12/7/2023 0 Comments Zen of python commandWe can always write and execute an ugly but working code without focusing on readability. This heuristic in the zen of Python says that we should always write clean and readable code. Now, we will discuss each statement in the zen of Python with examples to understand them in a better manner. You can obtain all the statements in the zen of Python by executing the command “import this” in the Python terminal or IDLE as shown below. Namespaces are one honking great idea - let’s do more of those!.If the implementation is easy to explain, it may be a good idea.If the implementation is hard to explain, it’s a bad idea.Although never is often better than *right* now.Although that way may not be obvious at first unless you’re Dutch.There should be one– and preferably only one –obvious way to do it.In the face of ambiguity, refuse the temptation to guess.Special cases aren’t special enough to break the rules.The statements in the zen of Python are as follows. The Zen of Python is a collection of 20 guidelines or heuristics suggested by Tim Peters. This article discusses the zen of Python with examples to help you understand how to write better code in Python. One such collection of guiding principles is the Zen of Python. With PEP (Python Enhancement Proposals), developers and computer scientists often suggest changes and principles for the Python programming language. Sudo cp _btrievePython.so /usr/local/actianzen/lib64Įxport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu:/usr/local/actianzen/lib64Every programming language has some guiding principles. Sudo cp btrievePython.py /usr/local/actianzen/lib64 G++ -shared btrievePython.o -o _btrievePython.so -L/usr/local/actianzen/lib64 -lbtrieveCpp G++ -c -fPIC -Iinclude -I/usr/include/python3.8 btrievePython.cpp Swig -cppext cpp -outcurrentdir -python -c++ -Iinclude -o btrievePython.cpp swig/btrievePython.swig It is assumed that Zen is already installed and running. In this example, we will target an Ubuntu Linux 圆4 environment. Using Btrieve with Python on Ubuntu Linux 圆4ĭocumented below is one approach to configuring the Btrieve 2 SDK for the Python programming language. You may need to allow everyone to write to the current directory if you receive the error "AssertionError: Error: BtrieveClient.FileCreate():94:Permission error". You should see the output "record: (9, 81, 3)". You may need elevated permissions to perform these copies.Įxecute the Btrieve Python sample program.Ĭ:\Python36\python.exe samples\btest.py 9 ![]() Note that the path to Python used above may differ.Ĭopy btrievePython.py "c:\Program Files\Actian\Zen\bin"Ĭopy _btrievePython.pyd "c:\Program Files\Actian\Zen\bin" ![]() Link -dll win64\x86_64\btrieveCpp.lib -libpath:C:\Python36\libs -out:_btrievePython.pyd btrievePython.obj Note that the path to SWIG used above may differ.Ĭl -EHsc -c -Iinclude -IC:\Python36\include btrievePython.cpp Open the Visual Studio 圆4 Native Tools Command Prompt.Ĭhange directory into the Btrieve 2 SDK directory.Ĭ:\swigwin-3.0.12\swig.exe -cppext cpp -outcurrentdir -python -c++ -Iinclude -o btrievePython.cpp swig\btrievePython.swig Generate, build, and install Btrieve Python. Install the Btrieve 2 Windows SDK for Zen. ![]() Install SWIG and Python if not already installed. In this example, we will use Visual Studio 2015 to target a native Windows 圆4 environment. Documented below is one approach to configuring the Btrieve 2 SDK for the Python programming language.
